SPECIFICATION forming part of Letters Patent No. 316,057, datedApril 21, 1885.

' Application' Bled January 8l 1984. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. PITT, ar citizen of the United States, residing at Glenbrook, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Combined Vaste and Overflow Valves, of which the following is a specilication.

My invention relates to improvements in devices for controlling the waste and overflow Water from wash-basins; and the objects of my improvements are, first, to provide a positive cut-oft' valve for the basin, whereby bad odors and smells are prevented from ascending into the Waste or discharge pipe 5 second, to furnish means whereby the basin is relieved to prevent overflow; and, third, to aord facilities for the ready removal or withdrawal of the valves and their connections. I attain these objects by the construction shown in the accompanying drawings, in Which- Figure l is a vertical section of my improved device, showing the valve raised to open a communication from the waste-pipe into the discharge-pipe. Fig. 2 is a similar section showing the waste-pipe valve closed and the overflow-valve open. Fig. 3 isa cross-section taken on the line x :c of Fig. 2, and Fig. 4 is a fragmentary view of the device for connecting the weighted lever to the cylinder.

Let a, Fig. 2, represent a stationary washbasin provided with the usual apertures, b, in the side thereof for the overflow. c is the Waste-pipe leading from the basin into a cylinder, d. Within this cylinder, which may be designated as the receiving-cylinder, are arranged cylinders e and f. The outer cylinder, d, communicates, by a central opening, d', with the short cylinder g', leading to the sewerpipe, and this opening is closed by valve g when it is in its normal position, as shown in Fig. 2. The valve g consists of an annular plate, h, having an upturned iiange, h', to receive the bottom of the cylinder c, and provided with downwardly-projecting flanges i and i. i

A central bridge-piece, j, which serves as a guide for the stem of the valve, is provided with openings, (see Fig. 3 at l 1,) through which, when the overflow-valve 7c is open, as

shown in Fig. 2, lthe water from the cylinders e and fis exhausted into the chamber below.

A solid rubber ring, Z, incloses the valveplate, h, having a recess, Z,.in its top and bottom edge, to receive the edge of the plate and its pendent projection t', and its outer edge is beveled to correspond to the beveled seat of the valve. v

The valve-stem, which is composed of sections a', c2, c3, and a4, extends up above the marble b', surrounding the basin, and has on its extremity a knob, c', for convenience in handling it.

The valve It', which controls the overflow, is an annular plate having neck o, provided with threaded sockets to receive the threaded ends of the stem-sections a and a2.. This plate rests, when in its normal position, against the projection i', and closes the opening or openings in the valve g.

The bottom of the inner cylinder, f, is provided with threaded sockets e, to receive the threaded ends of the stem-sections e2 and c3. The other end of the section c3 and the lower end of section c4 screw into a link, n, which is slotted longitudinally to receive the inner end of the lever q, provided with weight r.

In the top edge of the outer cylinder, d, is provided a number of slots, s, into any one of which the plate t, forming the pivotal bearing for the lever q, may be adj usted as convenience or necessity requires. This plate t, to which the weighted lever g is fulcrumed, is formed with side lugs, t, and flanges u, which abut against the inner surface of the cylinder, as seen in Fig. 4E. The pivot-pin 'u secures the lever between the sides of the plate t.

A suitable aperture is formed in the marble to permit of the vwithdrawal of the two inner cylinders and connected valves for the purpose of repair or cleansing. A cap, w, secured by thumb-screws w, covers the aperture in the marble.

To the bottom of the cylinder d is secured an annular extension, g', formed of brass, spun up into the shape desired, with an inwardly-I beveled surface to form the seat for the valve g.

y represents a cast ring with an exterior threaded surface to connect with the dischargepipe leading to the sewer, and provided with IOO the bridge z, having openings therein for the passage ofthe water. This ring is inserted into the lower end of the cylinder g.

The water, iiowing from the basin through the waste-pipe c, will be received into the outer cylinder, d. By taking hold of the knob c` the valve-stem is raised, lifting valve g and allowing the water to be discharged into the cylinder below and onto the sewer-pipe, as indicated by the arrows in Fig. 1.

The annular plate k, which, as before stated, closes the communication between the central cylinder, e, and the cylinder g', forms the cutoff valve to control any overow from the.

basin, and its action is automatic, as follows:

Any excess of water discharging through' the side or overflow openings in the basin will follow the course indicated by the arrows in Fig. 2. First entering the cylinder d, (the valve g of course being closed,) it will by accumulation flow over into the middle cylinder, e, and on into the cylinder f. The lat ter cylinder will then be forced down by theV weight of its contained water, opening the valve 7c and allowing the water to discharge into the cylinder below. In the bottom por tion of the cylinder fare provided perforations f', for the escape of the water. As the cylinder f is relieved by such discharge, itwill rise, closing the valve 7c, as shown in Fig. 1.

By removing the cap w the cylinders e and f, with valvestem and attached valves, may be drawn out together, and the cylinder d be left open for cleansing or repairs.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination, witha stationary washbasin, of two upright receiving-cylinders, arranged one within the other and open at the top, the outer cylinder communicating directly with the waste-pipe, and provided with a valve-seat to receive a valve on the bottom of the second cylinder, and a valvestein having a slotted link-connection with a weighted lever, all arranged and operating as set forth.

valve-seat cl', in combination with the cylin.- y

der e, provided with valve g, having projections t' z" and central open bridge, j, and valve 7c, with attached valve-stem, as and for the purpose set forth.

4. The combination, with` the basin a and pipe c, of the'cylinders d, e, and f, valves g and k, with valve-stem, slotted link n, and weighted lever q, allarranged and operated as and for the purpose set forth.

5. The combination, with the cylinders d, e, and g', having the valveseat d', of the valveplate h, provided with projections z', and rubber packing-ring Z, having its upper and lower edges recessed to adapt it to receive and inclose the edges of the said plate and projection, as set forth.

6. The combination, with the cylinders d e g', with valve-connection and pipe c, of the open bridge-piece j, valve 7c, cylinderf, valvestem with slotted link n, and weighted lever q, as and for the purpose set forth.

7. The cylinder d, provided with slots in its upper edge, in combination with the plate t, constructed as shown, valve-stemvhaving slotted link n, and lever q, as and for the purpose set forth.
